. RECREATlON sueMARmE-soAToEvl-ce SPECIFICATION forming part of Letters Patent No. 743,816, dated November 10, 1903- Application filed May 23, 1902.

To all whom it may concern:

Be it known that I, FRANCIS W. BRADY, a citizen of the United States, residing in Englewood, in the county of Bergen and State of New .1 er'sey, have invented certain Improvements in Recreation Submarine-Boat Devices, of which the following is a specification.

. This invention relates to the class of recreation devices, and has for its object a boat,

with. propelling and steering means, which is adapted to run on the surface of the water in awaterway and which is also adapted to dive or be drawn under the water and run submerged for a predetermined distance in' order to give to the passengers the experience of making an excursion on a submarine boat.

The construction comprises a water-tight boat adapted to float in the manner of an ordinary boat and-to be submerged without taking inwater, and a fixed submerged guideway adapted to draw the beat down and under as it advances and to hold it submerged for a time. When the boat shall have traversed the length of the guideway and is free, its buoyancy'will again bring it to the surface.

In the accompanying drawings, which illustrate an embodi'mentof the invention, Figure 1 is a longitudinal vertical axial section'of the the deck in plan.

- boat. Fig. 2 is a sectional plan, the upper half being a plan of the superstructure and the lower half a horizontal section showing Fig. 3 is a transverse section at line as in Fig. 1. Fig. 4- is a transverse section of the boat on a larger scale than the principal views and showing the stud-wheels at the sides of .the boat in engagement with the diving-guideways. The left-hand side is a midship section, and the right-hand side is a section takeuat the aft bulkhead. Fig. 5 is a general view showing theboat in the water and a part of the fixed diving-guideway.

Respecting the boat itself, 1 designates the hull, which has somewhat the form of the well-known submarineboat, butis'constructed flatter on the bottom than in the real submarine type in ordertoreducethe natural buoyancy.

2 is the central portion or saloon, provided with seats 3., windows 4 at the sides, and. electhe way.

Serial No. 108,617. (lilo model.)

It may also have an electric tric lights 5.

6. Within the saloon is the ventilating fan ladder or steps 7,1eadin'g up to the hermetically-closable hatch 8 for entrance'and exit. At the forward bulkhead 9 is the steeringwheel 10, connected by tiller ropes or chains 10' with the rudder 11. Back of the aft bulkhead 12, which forms the limit of the extension of the saloon aft, is the engine-room, containing the electric motor 13 for driving the propeller-shaft 14, carrying the propeller 15. Themotor is supplied from storage batteries 16 under the seats or stowed in any couvenient place.

Figs. 1 and 5 show the preferred degree of submergence or draft of the boat .in surface running.

clearly in Fig. 5'.)

The operation of the recreation device is as .follows: The boat 13 takes on its passengers,

closes the hatch 8 hermetically, and starts on its trip or cruise,

seen at the left in Fig. 5. In due time it approaches the elevated end 9 of the guideway- G, where the guides-19 of the latter will be found sufilciently elevated to allow the stud-y wheels 20 on the boat to passv freely under them. As the boat continues to move ahead and the downwardly-curved.portiong' of the guides is reached the boat will begin to dive, its nose dipping under the water from the inclination o! theguidesl Thewheels 20 by and as herein shown there is a strong The stringers and guides on the guideway running on the surface, as

engaging the guides draw the boat down, as

. way may have any desired form, and-the The guides 19' will have guidewa'ys may be either tally curved, as desired.

Near thefan 6. there will he a telescopic ventilator 21. (Seen protruded upwardin Fig. 1.) This ventilator is in the nature of a tube and passes out of the boat at a packed gland 22. The ventilator may be protruded upward above the surface of the water when theboat is submerged.

The chamber 23 at the bow of the boat forward of the bulkhead 9 is open tothe water of flotation thro'ughan aperture or apertures 24, the object being to .provide a ballast for the bow of the boat to facilitate diving. When running on the 'surfac'e,this bow-chamber will be filledwith water up to the level of the water of flotation. The stud-wheels are merely convenient straight or horizonforms of laterally-projecting parts on the boat adapted to'engage the diving-guides 19, and their particular form, arrangement, and'eonstrnction are not essential to this invention. an elevated portion, as g, a depressed portion, as g", and an intermediate inclined portion, as g', and it is preferred to make this intermediate portion in tial to the invention.

the term of an ogee or reverse curve; but the particular form of this portion is not essen- Being the first, as I believe, to construct a recreation device comprising a ,fioatable and submergible boat provided with suitable.lat-

erally-projecting parts to facilitate diving and to'combine with this boat a fixed diving-.

guidewaywhollysubmerged in the waterway and adapted to engage the lateral projections on. the boat and cause the latter to dive as it advances, I claim this combination, broadly, as I am not aware that any one has ever contemplated the submergenceof the entrance end of-the guidewayas well as the main-portion, so that theboat may sail about the waterway and "on reaching the submerged entrance thereot enter the guideway and dive.

This greatly enhances the attraction, as the .entire guideway is concealed and out of the view of spectators;

Having thus described my invention, I

-claim 1. The combination, with a submergible boat, provided with means for closing it against the ingress of water to its inhabited part, with means for steering and propelling it, andwith laterally-projecting parts to facilitate diving, of a guideway wholly submerged, having guides adapted to engage and take overthe said laterally-projecting parts on the hoat and draw the latter, as it advances, down under the water, said guideway thus having its entrance below the surface so as to be invisible to spectators.

2. The combination with asubmergible boat, provided with means for steering and propulsion, with means for closing it against the ingress of water to its inhabited part, with a ballast-chamber at its bow open normally 'stnd-wheels 20 at its sides below the normal water-level, of the guideway, fixed and submerged and having guides 19, said guides having their elevated portions above the normal level'oic said wheels, and having depressed portions. connected with the said elevated portions by portions having a reverse curvature.

4. The combination with a submergible boat, provided with means for closing it 9 against the ingress of water to its inhabited it, with wheels at itssides, and with a ballastchamber at the bow open normally to the water of flotation, of a submerged and fixed guideway having guides adapted to engage and take over the said wheels on the boat and draw the latter, as it advances, down under the water.

5. The combination with a submergible boat, provided with means for closing it against ingress of water to its inhabited part,

with means for steering and propelling it, and with a water-ballast chamber at itsbow normally open to the water of flotation, of fixed,

part, with means for steering and propelling IIO submerged means, ina waterway, for drawing said boat under water as it advances.

In witness whereof I have hereunto signed my name, this 21st day of May, 1902, in the presence of two subscribing witnesse I Y 3 w FRANCIS BRADY. Witnesses:
